  • House Monitoring Cameras --> Computer Display

    My dad is thinking about setting up some cameras (around 4) around the house as a security measure. Those cameras would then be hooked up to a computer who's only purpouse would be displaying those feeds on the screen. I would then set up a VNC connection so he could see the feeds from wherever he felt like.

    I know how to set up the VNC and all of that, what I need to know is:

    -What kind of a system do you recommend to handle the camera inputs? ie: what should we be focused on in terms of a bottleneck: RAM, CPU, GPU, ect.

    -What resolution should of cameras would you recommend (and which brands) for the cameras? These are just for added security measures, but should be clear enough to distinguish faces at a good distance.

    -What kind of an input would you use from camera --> PC (through the vid card, USB, ect.)?

    Thanks in advance for all of your help :)

    There are a number of manufacturers of PCI based capture cards that will do this for you easily. They usually come in 4, 8 and 16 port varieties and run around $130 or so. You really don't need much of a machine to run them. Heck, you can probably run it off an old P4 or lower.

    The software is really where you've got the choices. Most of the software apps that run the system are TCP/IP accessible or even have their own web servers. You can hit them with a web browser from anywhere and even control the PTZ (Pan, Tilt & Zoom) functions of the cameras (if you have cameras with that capability).

    The most common cameras to use are of the "lipstick" variety and in most cases they are Sony CCD cameras in various third party housings. There is a wide variety of both B&W, Color and Color/IR camera options. Most start around the $75/each mark and go up from there.
    Diplomacy is the art of saying "good doggie" while looking for a bigger stick.
